Why TECNO Phone Battery Issues Happen in 2025

TECNO smartphones are known for their affordability, durability, and impressive features, but like any device, they’re not immune to battery problems. Understanding the root causes of battery issues is the first step to finding a lasting solution. Based on Carlcare’s extensive repair data and technician insights, here are the most common reasons TECNO phone batteries fail in 2025:

Overuse and High-Demand Apps

Modern smartphones, including TECNO models like the Camon 20 or Spark 10 Pro, are often pushed to their limits with heavy usage. Activities like gaming, streaming high-definition videos, or running multiple apps simultaneously can drain lithium-ion batteries quickly. For example, playing a graphics-intensive game like PUBG Mobile for just an hour can consume up to 20% of your battery, according to our internal tests.

Aging Battery Cells

Lithium-ion batteries, which power most TECNO phones, have a limited lifespan. On average, they can handle about 500 full charge cycles—roughly two years of daily use—before their capacity drops significantly. After this point, you might notice your battery holding only 80% of its original capacity, leading to shorter usage times. Carlcare’s 2024 repair data shows that 65% of Kenyan TECNO users reported battery drain issues within 18 months of purchase, often due to natural wear and tear.

Software Bugs and Background Activity

Outdated firmware or poorly optimized apps can cause excessive background activity, draining your battery faster than normal. For instance, apps that constantly refresh in the background—like social media platforms or messaging apps—can consume power even when you’re not actively using them. In 2025, we’ve seen a rise in battery complaints linked to software bugs, especially after major Android updates that TECNO devices receive.

Environmental Factors

Extreme temperatures can also affect battery performance. In Kenya, where temperatures can soar above 30°C in some regions, prolonged exposure to heat can degrade your TECNO battery faster. Conversely, very cold conditions can temporarily reduce battery efficiency, making your phone shut down unexpectedly. Carlcare technicians often advise users to avoid leaving their phones in direct sunlight or inside a hot car for extended periods.

Charging Habits and Accessories

Using non-original chargers or cables can harm your TECNO battery over time. Cheap, uncertified accessories may deliver inconsistent voltage, leading to overcharging or overheating. Carlcare’s service centers frequently see devices with damaged batteries due to third-party chargers, which is why we recommend using original TECNO accessories.

Step-by-Step Fixes for TECNO Battery Drain

Before rushing to a service center, you can try some simple troubleshooting steps to address your TECNO phone battery issues. These DIY fixes are safe, easy to follow, and can often resolve minor problems. However, if the issue persists, Carlcare’s professional services are just a click away. Here’s what you can do:

1. Check Battery Usage

Start by identifying which apps or processes are draining your battery the most. Here’s how:

• Go to Settings > Battery > Battery Usage.
• Look for apps consuming a high percentage of power (e.g., Instagram, WhatsApp, or games).
• Tap on the app and select Restrict Background Activity to limit its power usage.

This step can reduce unnecessary battery drain by up to 15%, based on Carlcare’s testing with TECNO devices like the Phantom X2.

2. Update Your Software

Software updates often include fixes for battery-draining bugs. To check for updates:

• Navigate to Settings > System > System Update.
• If an update is available, download and install it.
• Restart your phone to ensure the changes take effect.

If you’re unsure about updating your device, Carlcare offers free software updates at our Kenyan service centers. You can also download the latest firmware directly from our website.

3. Enable Battery Saver Mode

TECNO phones come with a built-in Battery Saver mode that reduces performance to extend battery life. To activate it:

• Go to Settings > Battery > Battery Saver.
• Toggle it on.
• Optionally, set it to activate automatically when your battery drops below 20%.

This mode can extend your battery life by up to 30%, making it a great temporary fix for heavy users.

4. Optimize Charging Habits

Overcharging or using improper charging methods can degrade your battery over time. Follow these best practices:

• Unplug your phone when it reaches 80% to avoid overcharging.
• Avoid letting your battery drop to 0% frequently; charge it at around 20%.
• Use only original TECNO chargers and cables, available through Carlcare’s accessory guide.

Safety Warning: Using uncertified chargers can overheat your device, damage the battery, and even pose a fire risk. Always opt for genuine accessories.

5. Reduce Screen Brightness and Timeout

Your screen is one of the biggest battery consumers. To save power:

• Lower your screen brightness in Settings > Display > Brightness.
• Set a shorter screen timeout (e.g., 15 seconds) in Settings > Display > Sleep.
• Disable adaptive brightness if you don’t need it.

These adjustments can save up to 10% of your battery daily, especially on TECNO models with large, high-resolution displays like the Camon 20 Premier.

6. Disable Unused Features

Features like Bluetooth, GPS, and Wi-Fi can drain your battery when left on unnecessarily. To turn them off:

• Swipe down to access your Quick Settings panel.
• Toggle off Bluetooth, Location, and Wi-Fi when not in use.
• Alternatively, enable Airplane Mode in areas with poor network coverage to prevent your phone from constantly searching for a signal.
